文摘
- •
Performance of RO membrane deteriorated due to use in desalination facility.
- •
PVA coating degradation led to increased organic fouling propensity.
- •
Bromine uptake by polyamide active layer led to reduced solute rejection.
- •
Both PVA degradation and bromine uptake led to decreased water flux.
- •
Bromination of polyamide active layer was not reversible by alkaline rinse.
